GEORGIE DORSEY, OF SEATTLE, WASHINGTON.

TELEPHONE ATTACHMENT.

Specification of Letters Patent. Patented M 1919.

Application filed April 20, 1918. Serial No. 229,798.

To all whom it may concern Be it knownthat I, Gnonoin DORSEY, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented new and useful Improvements in Telephone Attachments, of which the following is a specificatlon.

This invention relates to new and useful improvements in attachments for telephones, and the principal object of the invention is to provide means, operated by the receiver fork, for interposing a disinfected shield between the mouth-piece and the lips of the user.

This invention is an improvement over that described in Letters'jPatent No. 1244433, granted to me on Oct. 24th, 1917.

Another object of the invention is to provide a device of this character which is simple and durable in construction, reliable and efficient in operation and one which can be manufactured and placed upon the market at a minimum cos The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of part of a telephone with my invention applied thereto.

Fig. 2 is a front view. 1

Fig. 3 is a section on line 3-3 of Fig. 1.

Fig. 4 is a view of a modification.

Fig. 5 is a section on line 55 of Fig. 4.

Fig. 6 is an elevation of another modification of my invention applied to the wall type of telephone.

Fig. 7 is a plan view of the attachment shown in Fig. 6.

Fig. 8 is an elevation of a slightly different form thereof.

Fig.

10 is a top view thereof. 11 is a side View thereof.

As set forth in the before mentioned patent I provide a tank 1, which is adapted to contain a suitable form of disinfectant. and within this tank is normally located a shield or shutter, which is adapted to be raised from the tank to a position in front of the mouth-plece, so as to prevent any germs passing from sald mouth-piece on to the lips of the user. In said patent the shield must be ralsed by hand, so that unless a person is familiar with the use of the device he is likely to use the telephone without the shield.

In the present case I provide means for rendering the operation of the shield automatical, so that as soon as the receiver is removed from the fork, the shield will be raised.

In carrying out this invention I secure the tank 1 to the telephone by an arm '2, provided with a two part ring 3, which is clamped to the telephone. The tank 1 is provided with a guide-way 4 at one side, which receives a bar 5, which is secured at its upper end to the shield 6. This shield enters the tank through a slot in the top thereof as shown in the before mentioned patent. Said shield may be provided with slots as shown in said patent, or said shield may be provided with a plurality of holes instead of the slots, so that a person may talk through the shield into the mouthpiece.

A lever 7 is pivoted at one end to the rm 2, and has its other end provided with a slot 8. which is engaged by a screw 9, carried. by the bar 5. The pivoted end of the said lever is provided with teeth, which engage with teeth formed on the end of the lever 10, pivoted intermediate its ends to the arm 2, and having its other end forked to engage the fork 11 of the telephone. In this way, as soon as the receiver is taken oif the fork, and the fork rises, the shield will be raised by means of the connections shown.

When the receiver is put back on its fork the shield will be lowered into the tank.

In the modifications shown in Figs. 4 and 5, the lever 7 is provided with a curved end 7 instead of the teeth. and this curved end is engaged by the rounded end of the lever 10', having its other end curved, and engaging the under part of the fork 11. Spring 12 is carried by the pin 13 of the lever 7. and said spring tends to hold the said lever with the shield in raised position but the weight of the receiver acting on the lever 10' holds the shield in lowered posi- In the modification shown in Figs. 6 and 7 the improvement is applied to the wall type of telephone. In this form the tank 1 is connected with the. lugs I of the telephone mouth-piece by a clamping device 14, carried by an arm 15 connected with the tank. This arm is rovided with an extension 15 to which is pivoted the lever 16. This lever is connected with the shield as before, and is provided with a small end 16 beyond the pivotal point, which engages with a bell crank lever 17, pivoted to the arm 15' at 18. The other part of the said bell crank lever engages the under side of the fork. The lever 16 is engaged by a spring 16*, which tends to hold the shield in raised position. The shield is held within the tank by the weight of the receiver.

In the modification shown in Fig. 8, the form of the lever 16 is slightly different from that just described, as is also the bell crank lever 17'. This figure shows the tank as provided with a filling opening 19, and draining opening 20.

' In the modification shown in Figs. 9, l0 and 11 the shield 6' is made of sector shape instead of rectangular asshown in the other views and one corner is extended and pivoted to the tank as shown. A plate 25 is secured to the face of the tank and has its upper end spaced from the tank so as to form a recess to receive said extended end of the shield, and the pivot passes through both the tank and said plate. Said plate. is slotted as at 26 and the extended part of the shield is also slotted for a purpose to be hereinafter described. An arm27 is secured to the rear of the tank and its other end is provided with a semi-circular curve 28 to form one part of the ring for embracing the telephone, the other part of said ring being formed by the semi-circular plate 29. Said parts are connected together by screws or the like. This arm carries the pin 30 on which is pivoted the lever 31. The pin also carries the spring 32 having one end secured to the arm and its other end engaging the lever and tending to hold the same in its lowest position. The outer end of said lever is provided with a pin 33 which engages the slots in the shield and plate 25 so that the shield is actuated by the movement of said lever. said lever is provided with the hook 34 which engages the fork of the receiver so that the shield is held within the tank by the weight of the receiver and its fork resting on said hook.

While the tank 1 may be formed of any suitable material, I' prefer to form it. of glass, and to support the same on a light frame-Work of metal.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make such changes in the construction and The other end of in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

I What I claim is 1. An attachment for telephones, comprising a tank, containing an antiseptic, a screen therein, and means for automatically positioning said screen in front of the month-piece when the receiver is removed from its fork. I

2. An attachment for telephones, comprising a tank containing an antiseptic, a.

perforated screen in said tank, and a series of lovers connected with the shield, and engaging the fork of the receiver for positioning sa1d shield before the mouth-piece when the receiver is removed from its fork.

3. An attachment for telephones, comprising a tank containing an antiseptic, means for detachably connecting said tank to the telephone, a shield in said tank, and means for positioning said shield in front of the mouth-piece when the receiver is removed from its fork.

In testimony whereof I affix my signature.

GEORGIE' DORSEY.
